GOURSE-INDENTING ATTACHMENT FOR ROAD ROLLERS.

App1ication filed January 8, 1925. Serial No. 1,237.

To all whom it may concern:

Be it known that I, RAYMOND W. KEELnn, a citizen of the United States, residing at Galion, in the" county of Crawford and State of Ohio, have invented certain new and useful Improvements in Course-Indenting Attachments for Road Rollers, of which the following is a specification.

This invention relates to attachments for road rollers, and the general object of the invention is to provide means whereby in dentations may be made in the first course of any road which is to receive a hot top as a second course, these indentations being designed to anchor the second course very firmly to the first course and thus pre vent the breaking up of the road under heavy tralfic.

A further object of the invention is to provide an attachment of this character in cluding roller clamps which are adapted to engage a roller and clamp thereon and to carry chains extending across the face of the roller, these chains being adapted, as the roller moves over the first course, to press indentations into this first course, as previously stated.

A. still further object is to provide a device of this character which is very simple, which. can be readily put in place and readily removed, and which does not require the lifting up of the rear end of the tractor in order to apply the device to the roller.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawing, wherein Figure 1 is a side elevation of a road roller having my indenting device applied thereto;

Figure 2 is an elevation partly in section of the road roller showing the indenting device applied thereto;

Figure 3 is a fragmentary perspective view of one end of one of the sections 10 showing the manner in which the sections are formed at their ends.

Referring to the drawing, it will be seen that my attachment comprises two semicircular sections 10 of angle iron, the sections when placed together having a diameter equal to the exterior diameter of the road roller A. The angle iron at the end of each section is inwardly bent, as at 11, so that these inwardly bent ends of the two sections may be disposed in abutting THE GALION IR.O1 T WO-RKS &

relation. Each section, because of the fact that it is formed ofangle iron, provides a peripheral flange 12 and a vertical flange 13L -Tlie vertical flange 13 lies, when the device is applied to the roller, against the edge of the wheel rim, while the horizontal flange extends over the face of the frame. -The inwardly turned ends 11 have the flange 12 cut away, as at 14, this cut-away portion fitting over the rim of the roller A, and that portion of the flange 13 which is inward of the junction of portion 11 with the arcuate portion 10 is apertured, as at 15, for the passage of a bolt. The flange 12 is formed with apertures 16 at certain definite intervals as, for instance, at intervals of every five inches, and attached to these inwardly extending flanges 12 are transversely extending chains 17, the extremities of which are formed with open links 18 which engage in these apertures 16, it being understood that there are a pair of these clamps formed of the sections 10 on each side edge of the wheel and that the chain 17 lies across the face of the wheel. The two sections of each clamp are bolted together by means of bolts 19.

In the use of this device, these clamps are disposed upon the rollers proper of a road roller as, for instance, upon the rear rollers thereof, and then as the machine rolls over the relatively soft first course, the chains will make indentations in this first course. A hot top as, for instance, a top of asphalt is laid upon this first course and rolled. This hot top will thus be forced into the indentations of the first course and interlocked therewith so that the second course is anchored very firmly to the first course.

In the application of this device to the rollers proper of a road rolling machine, onehalf section of each clamp is set down on the wheel, these half sections, of course, being connected by the chains 17, then by turning the wheel around the other half section can be put on and both sections are then bolted together.

lVhile I have particularly designed this chain clamp and carrier for the rear rollers of road rolling machines, it will be obvious that it may be also applied to the front rollers and that it may be adapted to many different types of rollers. While I have described the use of chains 17 as the indentation forming means which are connected to the clamp sections, I do not wish to be limited thereto as it is ObVlOUS that other forms of flexible connection having means for forming indentations might be used.

I claim 1. An indentation-forming attachment for road rollers comprising oppositely disposed roller clamps, each clamp comprising a plurality of sections adapted to embrace the. rim of the roller, each section being formed of angle iron to provide a flange resting upon the rim of the roller and a flange extending vertically inward from the outer edge of the roller, means holding these sections in connected engagement with each other and clamped upon a wheel, and transversely extending flexible indentation-forming members engaged at the ends with said clamps.

2. An indentation-forming attachment for road rollers comprising two roller clamps disposed at opposite edges of the roller, each clamp comprising two approximately semicircular sections of angle iron to provide a flange resting upon the periphery of the roller and a flange disposed vertically against the rim thereof, the terminal ends of each section being inwardly bent to provide abutting portions and one of the flanges of the inwardly turned portions being cut away to accommodate the rim of the roller, bolts passing through said abutte-d portions to thereby hold the sections in engagement with each other and against the roller, and a plurality of transversely extending chains each connected at its ends to the rim flanges of the clamps.

In testimony whereof I aflix my signature.

RAYMOND W. KEELER.
